Hello,

 

I'm trying to get rotation information of a cell which come from a DGN.

I found it for text element but not on cell. In microstation the information is present but not in FME, do you have any idea ?

 

In the help here : https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/dgnstyler.htm it say :

OpenCell Rotation
 
Specifies rotation of the cell (in degrees counterclockwise from horizontal). This can be set to any floating-point value between -360.0 to 360.0, or be set to a value taken from an attribute.
 
Format attribute set: igds_cell_rotation

But I haven't this attribute in FME : 

CaptureBut here in Microstation you can see the information (50 g = 45 deg)

Capture

Did you look for igds_rotation / fme_rotation as well?

Hi @arnaudfouch​ I think you may need to expose the attribute in the DGN Reader Parameters in Format Attributes tab. Or using an AttributeExposerRotation

Finaly I find solution by analysing directly the entity with HorizontalAngleCaluclator
